No, Not really actually. Just make a space map like FF's where you run forever, only have the normal eggman at the end with a few Upgrades like Zeshiro, Also stuck within a blockenemy sector... So, you'd run up to him, attack, get flung backwards, run, attack, ect...
Then, you could increase his HP to something high, yet still beatable as supersonic, without running out of rings.
